Students were put in groups of 4 using visible random groupings.
Each group was given one of these equations.
y = x^3+4x^2+5x+2
y = x^3+5x^2+8x+4
y = x^3+5x^2+7x+3
y = x^3+6x^2+11x+6
y = x^3+7x^2+16x+12
Students were then told to get four different colors of cube-a-link blocks, enough of each color to generate each term from x = 1 to x = 4. Here is one groups work to figure out how many blocks they needed.
